Средняя продолжительность жизни пациентов с этим диагнозом составляет 9–12 мес. Для поиска эффективных подходов к терапии и диагностике этого заболевания требуется разработка адекватных экспериментальных моделей. В данной работе для описания динамики роста и морфологии клеток глиобластомы U87, ортотопически ксенотрансплантированной мышам иммунодефицитной линии SCID, мы использовали ряд методов магнитно-резонансной томографии (МРТ). Сравнение эффективности визуализации развивающейся опухоли с помощью Т1- и Т2-взвешенных изображений, полученных на сверхвысокопольном томографе Bruker BioSpec (11,7 Т), показало, что вследствие сильной продольной намагниченности магнитного поля томографа Т1-взвешенные изображения не дают необходимого контраста патологической ткани относительно здоровой в отличие от Т2-взвешенных изображений. Использование Т1-взвешенных изображений совместно с внутривенным введением наночастиц парамагнетика – оксида марганца (MnO) значительно усилило контраст опухоль/нормальная ткань на МРТ изображениях. Исследование динамики роста опухолевых клеток с помощью Т2-взвешенных изображений показало, что развитие опухоли начинается не раньше чем через 3 недели после интракраниального введения культуры клеток U87, при этом опухолевые клетки демонстрируют экспоненциальный рост. Таким образом, были отработаны и охарактеризованы методы Т1-, Т2-взвешенной и MnO-усиленной МРТ на модели ортотопической ксенотрансплантации клеток глиобластомы человека U87 иммунодефицитным животным SCID, которая может быть использована в качестве in vivo экспериментальной модели для проверки новых противоопухолевых препаратов и схем лечения онкологических заболеваний головного мозга человека.</p></abstract><trans-abstract xml:lang="en"><p>Glioblastoma multiforme (GBM) is the most common and lethal type of brain cancer with the average lifespan of patients about 9–12 months. The study of tumor formation and the evaluation of new therapies for GBM require accurate and reproducible experimental brain tumor animal models. In this study we used MRI for investigation of tumor morphology and growth dynamic in an orthopic xenotransplantation immunodeficient mouse model (SCID mouse line). Comparison of T1- and T2-weighed MRI scans preformed with a high-field MRI scanner (Bruker, BioSpec, 11,7 T) revealed insufficient tumor/normal tissue T1-contrast because of high longitudinal magnetization of the magnetic field in our scanner. Intravenous injection of paramagnetic manganese oxide (MnO) nanoparticles dramatically increased the tumor/normal tissue contrast in T1-weigthed MRI scans. The study of glioblastoma growth with T2-weighed images showed that a significant tumor development began not earlier than 3 weeks after cell culture intracranial injection and then the tumor grew exponentially. Thus, we developed a protocol of the characterization of glioblastoma U87 growth and morphology by T1- and T2-weighed and MnO-enhanced MRI in the orthopic xenotransplantation mouse model. The results demonstrate that this SCID model may be used as an in vivo preclinical model to test the efficacy and putative side effects of novel anticancer therapies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глиобластома U87</kwd><kwd>магнитно-резонансная томография</kwd><kwd>ксенотрансплантация</kwd><kwd>парамагнитные наночастицы оксида марганца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glioblastoma U87</kwd><kwd>MRI</kwd><kwd>xenotrasplantation</kwd><kwd>paramagnetic nanoparticles</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Минобрнауки России, Российский научный фонд</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abdollahi A., Schwager C., Kleeff J., Esposito I., Domhan S., Peschke P., Hauser K., Hahnfeldt P., Hlatky L., Debus J., Peters J.M., Friess H., Folkman J., Huber P.E.
